Final answer:
The question refers to Triprotic and Organic acids. Triprotic acids, such as phosphoric acid, have three dissociable protons, whereas Organic acids like acetic acid contain a carboxyl functional group. The correct types of acids are Triprotic and Oxyacid.
Step-by-step explanation:
The types of acids being referred to in the question are Triprotic acids and Organic acids. While 'Triprotic' refers to acids that have three dissociable protons, such as phosphoric acid, 'Organic' pertains to acids that contain a carboxyl group, like acetic acid. Triprotic acids undergo stepwise ionization and a typical example would be phosphoric acid, which ionizes in stages, each time releasing a hydrogen ion. Organic acids, such as acetic acid (found commonly in vinegar), butanoic acid, and benzoic acid, to name a few, all feature the carboxyl functional group: a carbon atom double-bonded to an oxygen atom and also bonded to a hydroxyl group (-OH).
As such, for the fill-in-the-blank question, the correct answers would be c) Triprotic; Oxyacid.
